"Oh my God, have you ever been robbed? I have. I’ve been physically robbed a couple of times, but this is much worse," she says of returning from a vacation in Tahiti and finding several unreleased tracks online. Though Clarkson wrote on her blog, "No point in getting angry because there’s nothing I can do so I hope y’all like the music," it turns out she really was upset, as she tells EW now:

"Those songs came out and people are like, 'Oh my God, what direction is Kelly going?' I think what made me mad was that: 1) People stole from me, and 2): Everybody had no idea what my next album was going to sound like. That really caused a lot of confusion."

Clarkson says all of the leaked songs were unfinished demos, many of which were songs she wrote for other artists and had no intention of recording herself: "There are songs out there that are from eight or 10 years ago … People are always asking me to write for other artists. They’re awesome songs, [but] they’re just not songs I would normally sing."

The Season 1 'American Idol' winner is finally ready to release her fifth album, 'Stronger,' which hits stores Oct. 25. Clarkson acknowledges that a couple of the leaked demos will appear on the record in their finished, polished form.
